Application filed June 16, 1913'. Serial No. 773,975.

To all whom, itmag concern:

Be it known that 1, JOHN W. Lnumuo, a citizen of the United States,residing at Groton, in the county of Brown and State of South Dakota,have invented certain new and useful Improvements in Ventilators; and Ido declare the following to be a full, clear, and exact description ofthe invention,'such as will enable others skilled in the art to which itappertains to make and use the same. a

This invention relates to improvements in ventilators, hot air registersand the like.

()ne object of the invention is to provide a ventilator having animproved construction and arrangement of air discharging passages andmeans for opening and closing the same whereby the air may be dischargedfrom the ventilator or register in any desired direction. 7

Another object is to provide a ventilator of this character having meanswh'eneby the air controlling shutters thereof may be readily operated.

iVit-h these and invention consists of certain novel features ofconstruction, and the combination and arrangement. of parts as will bemore fully described. and claimed.

In the accompanying drawings: Figure 1 improved ventilator; Fig. 2 rearview thereof showing part of the air controlling shutters in openposition and the other shutters in closed position; Fig. 3 is anenlarged irregular horizontal sectional view taken on the line 3-3 ofFig. 2 showing the-shutters in one side of the compartment closed andthe shutters in the other side or opposite compartment open; Fig. t is adetail perspective view of one of the shutter operatingmembers- Myimproved ventilator or register comprises a rectangular frame 1 havingon its outer edge, which are diagonally arranged partition bars 3 whichdivide the frame 1 into four triangularly shaped spaces or compartments4 as shown. Each of the spaces or com- .artments 4' has arranged thereinat the outer side thereof series of slats 5 the ends of which arepreferably formed integral. with the partition bars 3, said slats beingspaced suitable distances apart to form air discharging passages 6. Theslats 5 have their outer edges flush with the outer edges other objectsin view, the

wall engaging flanges 2 andin of the partition bars and with the outeredges of the flanged sides of the frame 1. The inner surfaces of theslats are concaved or curved from their inner toward their outer edgesas shown at 17 while the outer surfaces of the slats are beveled orformed at an angle as shown at 8. By con structing the slats in themanner described the passages between the same will be inclined and willdiverge from the center of the triangular compartments or spaces betweenthe partition bars, toward the adjacent outer sides of the ventilator orregister as is clearly shown in Fig. 3 of the drawing. By forming thepassages 6 in the manner de scribed it will be seen that the air passingthrough the ventilator or register will be discharged in four directionsfrom the center of the ventilator and will thus be more evenly oruniformly distributed into the room or compartment in which theventilator or register is arranged.

In order to control the discharge of the air from the ventilator orregister or to discharge the air in any desired direction, I provideshutters 9 for opening and closing the passages 6 between the slats 5.The shutters 9 are hinged at their outer edges to the inner ends of theslats 5 Fig. 3 of the drawings and the inner or free edges of theshutters are curved to conform .to theportionof the curved inner surface'of the ad acent slats with which said free edges of the shutters areengaged when swung to a closed position as is clearly indicated in theleft hand side of the, compart ment in Fig. 3 of the drawings. \Vhen inan open position the shutters project inwardly at right angles to theinner ends of the slats as clearly indicated in the right hand side ofFig. 8 of the drawing. 7 By arranging the passages and the shuttersthcrc-' for inthe manner described it will be seen that when it isdesired to direct the air from the ventilator or register to the rightas shown in Fig. 3 0f the drawings it is simply necessaiy to open theslats in the right hand compartment or space 4 of the ventilator and toclose the shutters in the remaining spaces whereupon all of the air willbe discharged from the spaces in the right hand side of the ventilator.in like manner whenitis desired to discharge the air in any otherdirection the shutters of the compartment corresponding to this diasshown at in flange 2 of rection are opened while the shutters in theremaming compartments are closed as will be readily understood.

shutters from the outside of the ventilator or register, I provideshutter operating levers 11 each of which is provided'with anintermediate portion 12 which passes 'through an aperture 13 formedbetween the outer slat and the adjacent inner side of the frame and ismounted in a bearing 14 arranged on the inner side of the frame asshown. ()n the outer end of the intermediate bearing portion 12 isformed a right angular projecting crank arm 15 overlying the the frameand which preferably works in a segmental recess 16 formed in the outersurface of the flange opposite one corner of each of the compartments orspaces 4. The inner ends of the lovers 11 are formed into fingers 18,project at a suitable angle from the inner ends of the hearing portionsof the levers and are pivoted to them at 17. These fingers looselyengage elongated eyes 19 arranged in shutter connecting bars or links 20which are pivotally connected to the inner free edges of the shutters asclearly shown in Fig. 3 of the drawings. 'When' thus arranged it will beseen that in order to open and close the shutters in any of thecompartments or spaces 4 of the ventilator it is simply necessary toturn the crank arms 15 of the levers 11 in the proper direction whichwill cause the fingers to swing the shutters to an open or closedposition as will be readily understood.

From the foregoing description taken in connection with the accompanyingdraw ings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described my invention, What I claim is:

1. A ventilator, register, or the-like comprising a rectangular frame,diagonal partition's in saidframe whereby the latter is divided intotriangular compartments, slats in said compartments having theirsurfaces constructed to form between'the slats dis- In order to readilyopen and close the charged passages diverging from the center of theventilator, and means to control the discharge fromsaid compartmentsindependently.

2. A ventilator, register, or the like comprising a square frame,diagonal partitions therein dividing the same into triangularcompartments, a series of parallel slats in each compartment whose innersurface is curved and whose outer surface is beveled, both surfacesinclining away from the common centerof the frame, and means to controlthe discharge through any compartment.

3. A ventilator or the like comprising a frame, a series of parallelslats therein Whose inner surfaces are curved and whose outer surfaces"are beveled and all of whose surfaces incline toward one side of theframe, a series of shutters hinged to the inner edges of said slats androunded alon their free edges to contact with the curve inner surfacesof the slats next adjacent, and means forswinging said shutters inunison.

4. A ventilator or the like comprising a frame, a series of parallelshutters hinged therein, a rock shaft journaled in the frame and havinga crank handle at its outer end and a finger. at its inner end, a linkconnecting said shutters, and an eye in said link through which saidfinger slides.

5. A ventilator or the like comprising a frame, a series of parallelslats in the frame, a series of shutters hinged to said slats, the framehaving a in its outer surface with a segmental recess, a rock shaftjournaled in the frame and having a crank arm at its outer end lyingwithin said recess and a finger pivoted to its inner end, andconnections between said finger and shutters.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
